Description
Röntgenologisehes Kontrastmittel. Durch das Hauptpatent wird ein rönt- genologisches Kontrastmittel, bestehend aus einer wässerigen Lösung eines jodmethan- sulfosauren Salzes geschützt.
Bei der weiteren Bearbeitung wurde ge funden, dass nicht nur die Lösungen von Salzen der Jodmethansulfosäure selbst, son dern auch die Lösungen von Salzen solcher Jodmethansulfosäuren, die durch gesättigte Gruppen aliphatischer Art, das heisst offene und zyklische Reste von aliphatischem Cha rakter substituiert sind, in hervorragender Weise zur röntgenographischen Darstellung von Hohlsystemen des Warmblüterorganismus geeignet und in der in dem Hauptpatent ge schilderten Weise anwendbar sind.
Beispiel: 20 gr des Natriumsalzes der 1-Jodäthan- 1-sulfosnure werden in 100 cm' Wasser ge löst. Die so erhaltene Lösung kann einem durch entsprechende Diät vorbereiteten Mes sehen innerhalb 1 bis 2 Minuten intravenös injiziert werden. Wird wenige Minuten später in üblicher Weise eine Röntgenaufnahme her- gestellt, so erhält man ein naturgetreues Bild der Harnwege.
Zum . gleichen Ergebnis gelangt man, wenn man an Stelle der wässerigen Lösung des Salzes der 1-Jodäthan-l-sullosäure wäs serige Lösungen der Salze von Jodmethan- sulfosäuren, die durch andere Alkylreste oder alizyklische Reste substituiert sind, verwendet.
Radiological contrast agent. The main patent protects a radiological contrast agent consisting of an aqueous solution of an iodomethane sulfonic acid salt.
During further processing it was found that not only the solutions of salts of iodomethanesulfonic acid itself, but also the solutions of salts of such iodomethanesulfonic acids, which are substituted by saturated groups of an aliphatic type, i.e. open and cyclic residues of aliphatic character, in excellent way for the radiographic representation of hollow systems of the warm-blooded organism and are applicable in the manner described in the main patent ge.
Example: 20 grams of the sodium salt of 1-iodoethane-1-sulfonic acid are dissolved in 100 cm of water. The solution obtained in this way can be injected intravenously within 1 to 2 minutes into a measurement prepared by an appropriate diet. If a few minutes later an X-ray is taken in the usual way, a lifelike picture of the urinary tract is obtained.
To the . The same result is obtained if, in place of the aqueous solution of the salt of 1-iodoethane-l-sulloic acid, aqueous solutions of the salts of iodomethane sulfonic acids that are substituted by other alkyl radicals or alicyclic radicals are used.
